ment in Filling Clamping and Parting Mechanism for Looms, of which the following description, in connection with the accompanying drawing, is, a specification, like characters on the drawing representing like parts. 1

This invention relates to automatic filling replenishing looms wherein the running filling is replenished prior to complete exhaustion and wherein the old or spent filling is parted between the cloth and the shuttle by parting means mounted upon a carrier, such as the usual swinging shuttle feeler, so as to be moved bodily,rearwardly and forwardly or toward and from the lay.

The object of the invent-ion is to provide an improved, simple, and effective means for operating the filling clamping and parting device when, and only when, a fresh filling carrier is transferred from the magazine or supply to the lay.

of the device and the parts of the filling clamping and parting means to be readily assembled and adjusted without the requirement of a high degree of accuracy.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings; a Fig, 1 is a transverse section of a portion of an automatic filling replenishing loom with a preferred form of the present invention embodied therein, the filling clamping and parting device being shown in forward or inoperative position;

Fig. 2 is a detail of a portion of the con struction shown in Fig. 1 with the filling clamping and parting device shown in rearward or operative position;

Fig. 3 is an end elevation partially in vertical. cross section of a portion of the construction shown in Fig. 2.

The construction illustrated is that of the invention is necessary.

a the lay well-knownNorthrop type of automatic filling replenishing loom, and as this/construction is familiar to those skilled in the art no detailed illustration or description beyond the features particularly concerned with this The broad feature of insuring the operation of the filling clamping and parting means when, and only when, afresh filling carrier is transferred from the magazine to :,tt1,084:,878 granted January 20, 1914 and this patent also serves to illustrate the general type of mechanismin connection with which a preferred form of the present invention is herein illustrated. The present invention is also subsidiary to the invention disclosed in the application to Edward S. Stimpson N0. 459,508, filed'May 14, 1921.

In the present invention a yielding or resilient actuator or actuator lever is employed to transmit motion fromthe ordinary moveable filling carrier support to the moveable member of the filling clamping and parting device and this resilient actuator lever is permanently mounted upon the moveable carrier for the filling clamping and parting means so that it is permanently located in the required position and is moreover readily attached to existing loom constructions.

The lay 1; the transferrer Qwhich upon the call for filling replenishment acts to transfer the filling carriers, or in this case the bobbins 3, from the magazine or hopper a to the lay, or in this case to the shuttle 5, at the replenishing side of the loom; the controller rock shaft 6 which is rocked upon the indication of substantialexhaustion in the running shuttle and actsto initiate filling replenishment; the breast beam 7 the shuttle feeler arm 8 which rocks and slides on the stud 9, being swun over the lay in front of the boxed shuttle upon the operation of the controller rock shaft 6 and returned under the action of the spring 10 are parts the con struction and operation of which will readily be understood by one familiar with the art such as is disclosed in the patent to Davis above mentioned and the patents therein referred to.

is disclosed in the patent to Davis,

rier to be transferred is yieldingly supported and gui'ded on the side opposite to the stop 11 by the usual movea ble filling carrier support 12 in the form of a'flat finger located adjacent the inner face "of the magazine. This supporting finger 12 is connected to a stud l 3'ex'tendilrg through the side of the magazine and carrying on the opposite side an arm 14. A spring 15 is held between a in .16 on, the magazine and the head @17 of aside rod 18 connected with the arm 14', the rod beinggui'ded in. the lug. The stop 11 thus forms one side of a throat which the filling carrier gpasses through from the magazine to the lay, the filling carrier support or finger12 forming the other side. When the transferrer 2 is operated to transfer a fresh .filli ng cam'ier from the magazine to the lay,

I The moveable blade woo-operates with fixed blades, one of which is shown at 20, and secures its opening and closing movement about the pivot 21.

When a replenishment of filling is called for, the shaft 6 is rocked in the usual manner raising the arm '22 extending rearwardly therefrom and therethrough rocking the shuttle feeler 8 toward the lay. If the shut- I tle is properly boxed, this feeler will pass in front of the shuttle in the usual manner and the lug 23 will be brought into the path of a hunter on the lay and thereupon the transferrer 2 will be operated to transfer the filling carrier 3 from the magazine to the lay there beneath.

When the shuttle feeler thus swings rearwai'dly over the lay, the filling extending from thefilling carrier to be abandoned enters between the members of the filling lates the filling clamping and parting de vice is closed to clamp and part the filling clamping and parting device which are then in open position. In the case of the type of mechanism to which this invention rejwhen, and only when, a filling carrier is actually transferred to the lay.

The desired result is secured in the present inventionby operating the filling clamping and parting device through the movement of the filling 'carrier support 12 which only moves when actual transfer takes place.

The present invention provides a yiel'dable or resilient actuator lever permanently fulcrumedon the shuttle feeler and so arranged as to be struck and moved by the filling carrier support to actuate the filing clamping and parting means when the latter in rearward operative position and actual transfer takes place. Thus, in case of any abnormal resistance there will be no danger of a smash or damage to the loom because the actuator lever will yield. So also it is unnecessary to provide any close or accurate adjustment of the various parts of the mechanism including those I of the filling clamping and parting means so long as the closing operation is insured. Any further movement which takes place thereafter will be taken up by the yield of the resilient actuator lever. The permanent location of the actuator lever on the shuttle feeler enables the invention readily to be applied to existing looms and insures at all times the proper relation of the actuator lever to the mechanism of the loom.

This resilient actuator lever in the construction illustrated is shown as formed from wire bent into the required form. At

its central portion it isibent to form a straight fulcrum portion 2 1. And this fulcrum portion is journalled in a bearing plate 25 secured to the top of the shuttle feeler 8 by screws 26. The forward portion of the actuator lever is bent to form a seat 27 arranged to hook under a pin 28 extended'laterally from the forward end of the moveable blade 19. The rearward portion 29 of the actuator lever is .bent rearwardly so as to stand, when the filling clamping and parting device is in rearward or operative position, directly beneath a stud 30 extended laterally from the arm 14 connected to the moveable filling carrier support.

It will thus be seen that, when the filling clamping and parting means have been car ried by the shuttle feeler into the rearward or operative position to embrace the filling extending from the filling carrier to be abandoned that the parts will stand sub stantially in the position shown in Figure 2. If now a filling carrier 3 is actually transferred to the lay the filling carrier support 12 will be rocked and the stud 30 will engage and rock the actuator lever and close the moveable member of the filling clamping and parting means thus causing the filling to be clamped and parted. If, for any reason an abnormal resistance to the movement of any of the parts occurs the resilient quality of the actuator lever will cause it to yield preventing injury or dam age. So also it will be seenthat no accurate adjustment of the parts is necessary because any movement which takes place after the moveable blade has closed is taken up by the yielding of the actuator lever.

The movement of the filling clamping and parting device to open or inoperative position is effected by the usual switch cam 31 co-operating with the outer end of the pin 28 in the usual manner. There is thus provided a very simple and practical mechanism readily attached to existing looms, readily adjusted to existing conditions and of strong and ellicient construction.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is: r

1 An automatic filling replenishing loom comprising a lay, a replenishing magazine "for the fresh filling carriers, means tor transierring a fresh filling carrier from the magazine to the lay, a filling clamping and parting device, a support for the filling clamping and parting device moveahle toward and from the lay and acting to position the filling clamping and parting device to receive the running filling when the lay is in position for transfer, a moveable filling carrier support moved by the filling carrier upon its discharge from the magazine to the la a resilient actuator lever fulcrumed transversely of and on the support for the filling clamping and parting device and hav ing one arm extending forwardly and engaging at its end the inoveable member of the filling clamping and parting device and having the other arm extending rearwardly and beneath the filling carrier support When the parts are in rearward operative position whereby upon transfer taking place the actuator lever will he moved by the filling carrier support to operate the filling clamping a d parting device to clamp and part the nning and will yield upon the occurrence of an abnormal resistance,
